GEORGE E. MITTINGER, JR., OF CASTLE, PENNSYLVANIA.

2o all whom 'it may concern:

Be it known that I, GEORGE E. MITTINGER,

-I Jr., a c itizen of the United States of America, residing at New Castle, -Lawrence'and State'of Pennsylvania, have in the county of invented certain new and useful Improvements in Coli'ee-Percolators,l of which the following is a specification, reference being 'had therein to the accompanying drawing. 1 0

colfee percolators.'

My invention relates to improvements in The object ofi my invention is to provide a l V` coffee percolator in which the heat applied is concentrated directly underneath. the

15 i frapi'dly and start when the heatis distributed throughout thevalve, which causes 4the valve to work more much morequickly than enti're bottom of the pot.l Another object of my inventionis to pro- -vide a more simple, cheap and effective device to'accomplish the desired' results.

In the accompanying drawings, Figure 1 is a vertical, sectional View of a coee pot einbodyingmy invention; zonta'l, sectional View taken on the line 'ax-:v of Fig; 1. Fig. 3 is an enlarged' botttoin plan view of the va'lve Vsea-t 'and valve. Fig.

Referring now 'to-the drawingsfl repre-- sents the-coffee pot whichmay be of any desired form but preferably ,the draw'ngsfhavin the'spout 2 and the oppositelyarranged andle 3, all of whichv of 'that shown in might be Y'vari'ec'l'as desired.

The 'pot is providedwith the usual mouth,

The body of the basket as shown, is a slight distance from the mouth ofthe pot, having the space 14 lsurrounding the same. Adjacent the upper end on oppositesides,

the bayonet slots 15 andl. The cover- 17 ,is preferably made of. glass, in order that readily see when the percolator tion, and is of an oval form'for anyone may is in operathe purpose The cover is provided with an v.outwardly extending flange 18, resting' upon the annular flange of the basket. The vertical wall' 19 ofthe cover extending.' within the basket, is provided with lugs and 21 which enter the bayonet. slots 15 and 16 'and whereby the cover is locked upon the basket and the basket being loosely or removably 11iou1ite'd..wit liin the p ot,it will be seen that the basket can be removed with the cover.

Carried by the c ent'er'of the bottom 12 is a -tube- 22 which extends up above the upper e cover 17. 'lhe tube has a washer 23 soldered' thereon and by means'of which the bottom ofthe basket may be more rigidly secured to the tube.

'The upperendof the tube is closed and is provided With'a series of small o eni'ngs 24: through which the water passes, all of which will be hereinafter niore fully described.

The lower end of the tube 22 has-secured thereto the cone sha ed member 25 which as shownq is compose of two plates 26 and 27 spaced a distance apart and the upper plate 26 has its outer lower end turned downwardly'at 28 and crimped to the lower plate 27. The upper end of plate 2G is solered4 or otherwise secured to the 'tube 22. The plate 27 has an open upper end 29 which is closed by the upper end 7 of the cone bottom of thejeofi'ee pot. The plates 26 and 27 aieparallel and are set at a different in the plate 27. The pot the receplwcle, a tube extending downwardly through the basket, a cone-shaped pocket carried by the lower'end of the tube and the lower wall of the pocket being conical and angle to the cone bottom of the pot, in order 1 that there be a slight space between the cone bottom of the pot and the plate 27 to allow the water to pass under said plate. The l plate 27 is provided with a series of openy of an angle difterin from the angle of said ings 30 through which the water passes to a bottom and said wa l having a. central openspace between the plates 26 and 27 as will be ing directly below the tube and into w ic hereinafter more fully described. lVithin the space 81 is the valve 32 which is of a cone shaped form and resting flat upon the l surrounding the central opening. lower plate 27 and closing the openings 30. l 2.
